Bicycle and Pedestrian Plan Initial Study Discussion of Checklist Items Less- than Sign ficant Impact The proposed Master Plan itself would not remove any trees. When implementing projects of the proposed Master Plan, the location of any trees and their potential significance, if any, will be considered in the project specific environmental review. It is anticipated that any future impacts regarding tree removal would be less than significant due to mitigation requirements of the Pleasanton Municipal Code, Chapter 17.16: Tree Preservation. In addition, the Master Plan would not conflict with an adopted Habitat Conservation Plan, Natural Community Conservation Plan or other approved local, regional, or state habitat conservation plan as no construction is included as part of the proposed Master Plan. No changes within existing roadways or otherwise developed areas would be likely to have any impacts on such plans, and these impacts would be less than significant. Projects due to Master Plan implementation that are located within natural areas could potentially have conflicts with conservation plans, could have a substantial effect upon an important species, or could conflict with the movement of any native or migratory species. Such impacts will be considered in project- specific environmental review under the CalOrnia Environmental ,Quality lct, if warranted, before project approval. No Impact. The proposed Master Plan itself would have no impact on any special status species, riparian habitat, or migratory bird species.

Environmental Setting The Northwest Information Center found 24 recorded Native American archaeological and historic cultural resources listed within its Historical Resources Information System.' Native American sites in Pleasanton range from large villages to small resources processing areas (e.g. for making acorn meal). These sites tend to be situated along ridges, on mid -slope benches, in valleys, and adjacent to intermittent and perennial watercourses. Pleasanton includes all of these features. In addition, Pleasanton is situated atop a formerly extensive marsh and pond system (the former Willow Marsh). Archaeological sites in Pleasanton include a prehistoric camp or temporary village; a prehistoric 2 /Allan Guldenbrein, California Historical Resources Information System, February 11, 2008.
